Muzak is background music played in stores, over phones on hold, etc. The term is also used to refer to various forms of popular music such as rock, pop, and rap, implying (correctly) that they are simplistic, crude, and lacking in artistic merit.

I can't believe you actually enjoy that muzak churned out by greedy corporations with no interest in art.

An actual company that once produced instrumental music for business use. Now mixes original artist music for almost every major company (and small ones) in the world. The name comes from Music + Kodak, NOT Music + Prozac.

Muzak hasn't produced elevator music in decades - so blame someone else.

Word used to describe the shitty music that is raping our airwaves and souls in America. Its produced to entertain the short attention span of soccer moms when they are in elevators and cubicles. Its spelled differently because it has more in common with prozak than it does with music. Its production proccess is also similar to that of prozak.

Repetitive music playing in malls, elevators, swimming pools, etc.
Usually renditions of classic or pop songs without the original lyrics. Management prefers this because it is cheaper and they think it is more "relaxing" than the actual songs. Derived from Music + Prozac.

When I called tech support, they put me on hold for 20 minutes forcing me to listen to horrible muzak!
